Example 4: Suitable for Leather Surfaces of Different Color and Texture

The appearance performance of compositions in accordance with thepresent disclosure was measured and tested for a variety of leathersurfaces. A composition in accordance with the present disclosure wasapplied three times on one side of a leather piece, while the other sidewas left untreated. The feel of leather was rated on a scale of 1-5,with 1 being the best (normal leather feel) and 5 being the worst (feelunlike leather).

Compositions in accordance with the present disclosure worked well onall leather colors tested, as well as on perforated and heated seats.The results are shown in FIGS. 16-22 and Table 10. In each case, thefinish applied to the leather had a non-greasy look and feel. The feelof the leather was not compromised. The compositions did not leavebehind a hard film at all.

This written description uses examples to illustrate the presentdisclosure, including the best mode, and also to enable any personskilled in the art to practice the disclosure, including making andusing any compositions or systems and performing any incorporatedmethods. The patentable scope of the disclosure is defined by theclaims, and may include other examples that occur to those skilled inthe art. Such other examples are intended to be within the scope of theclaims if they have elements that do not differ from the literallanguage of the claims, or if they include equivalent elements withinsubstantial differences from the literal language of the claims.

As used herein, the terms “comprises,” “comprising,” “includes,”“including,” “has,” “having,” “contains”, “containing,” “characterizedby” or any other variation thereof, are intended to cover anon-exclusive inclusion, subject to any limitation explicitly indicated.For example, a composition, mixture, process or method that comprises alist of elements is not necessarily limited to only those elements butmay include other elements not expressly listed or inherent to suchcomposition, mixture, process or method.

The transitional phrase “consisting of” excludes any element, step, oringredient not specified. If in the claim, such would close the claim tothe inclusion of materials other than those recited except forimpurities ordinarily associated therewith. When the phrase “consistingof” appears in a clause of the body of a claim, rather than immediatelyfollowing the preamble, it limits only the element set forth in thatclause; other elements are not excluded from the claim as a whole.

The transitional phrase “consisting essentially of” is used to define acomposition or method that includes materials, steps, features,components, or elements, in addition to those literally disclosed,provided that these additional materials, steps, features, components,or elements do not materially affect the basic and novelcharacteristic(s) of the claimed invention. The term “consistingessentially of” occupies a middle ground between “comprising” and“consisting of”.

Where an invention or a portion thereof is defined with an open-endedterm such as “comprising,” it should be readily understood that (unlessotherwise stated) the description should be interpreted to also describesuch an invention using the terms “consisting essentially of” or“consisting of.”

Further, unless expressly stated to the contrary, “or” refers to aninclusive or and not to an exclusive or. For example, a condition A or Bis satisfied by any one of the following: A is true (or present) and Bis false (or not present), A is false (or not present) and B is true (orpresent), and both A and B are true (or present).

Also, the indefinite articles “a” and “an” preceding an element orcomponent of the invention are intended to be nonrestrictive regardingthe number of instances (i.e. occurrences) of the element or component.Therefore “a” or “an” should be read to include one or at least one, andthe singular word form of the element or component also includes theplural unless the number is obviously meant to be singular.

As used herein, the term “about” means plus or minus 10% of the value.
